It will be apparent to those skilled in the art to Wh-ich this invention appertainsthat changes may be made in the details of the invention without departing from the spirit and scope cf the appended claims.-

Having thus described the inventidn, what I claim as new and desire to sec'ure by Letters Patent is 1. In a railway car comprising a plurality of connected bodies, a truck for supporting the adjacent ends 0f two of said bodies, a side bearing on each of said ende, and an anti-friction side bearing 011 said truck.

adapted to engage with said bearings and be movable universally in a horizontal plane thereby. y

2. a railway car comprising a plurality 0f conne'cted bodies, a truck for supporting the adjacent ends of two of said bodies, a side bearing on each of said ends, and a roller side bearing on said truck adapte d to engage with one of the body side bearings, on ea ;h of said ends.

3. In a railway car comprising a. plurality of connected bodies, a truck for supporting the adjacent ends 01": two ofsaid bodies, a body side bearing on each of said ends and a yieldable n1;i-friction side bearing munted on said truck adapted to engage with one o'f the said bo ends.

4.- In a railway car compri sing a plurality of connected bodies, adjacent ends of. two0f said bodies, a body side bearing on each of said ends', a truck side bearing coxnprising a plurality cf 1005ely mounted members adapted to engage with y side bearings on each of said said body side bearings, and means on said body side bearinga rotary 1novement memb'ers.

5. A truck side bearing for articulated adapted to prevent undue of said loosely mounted cars comprising a base portion and a Plurality of shoe members yieldably m0unted on rsa1id base, each of said shoe members comprising a plurality of bearing rollers.

a truck supportingt-he adjacent ends of said bodies, 'ings interposed b'etween said ends and truck,

6. In a railway car comprising a plurality of bodies, ends of two of said bodies, and universally movable toller side bearings interposed betwee'n said ends and truck.

{ 7 In a railway car comprising a plurality of bodies, a truck supporting the adjacent ends of two of said bodies, and yieldable roller side bearings between said endshnd truck.

8. In an articulated car comprising a plurality of ca r bodies, a truck supportingthe adjacent ends' of two of said bodies, und anti-friction side bearings for sid bodies, eachof said side bearings c'oinprising abase member mounted on said truck, a plurality 0f shoe mernbers yieldably mounted in said base member, and rollers loosely mounted in said shoe members adapted to'be engage by said-bodies.

9. A side bearing for articulated cars, comprising a base portion, a. plurality of resilient members mounted in said base ortion, vertically movable members mouhted on said resilient members, shoe members mountedon said vertical]y movable members adapted to swivel relative to said members and bearing rolleis carried by said shoe meinbers.

10. A side bearing for articulated cars con1prising a base portion havingspaced recesses formed therein, resilient members mounted in said recesses, shoe members yield-- ably su1 ported' by said resilient means, and bearing rollers carried by said shoe members, and movable bodily relative thereto.

111 A side bearing for the adj'acent erids 0f two adjace-nt bodies of an articulated car comprising a pluraliry 0f yieldably supported and bodily m ovable rollers.

12. In an articulated car comprising a plurality 0f car bodies, a truck supp0rting the and side bearsa1d b6aring3 each comprising a plurality of bodil-y movable rollers adapted to'be engaged by said bodies.
